An adjustable bed includes a mattress frame having pivotally interconnected sections, a main or base frame supporting the matress frame and telescoping leg assemblies. A first motor drive actuator is supported on the main frame. The first actuator engages a crank arm or lever fixed to a head section of the mattress frame. A second actuator is mounted on the base frame. A second actuator engages a crank arm attached to a knee section of the mattress frame when the actuator is moving to a fully retracted position. A cable carrier is engaged by the second actuator as it moves to a fully extended position. A cable assembly interconnects the cable carrier with the telescoping leg assemblies. The second and moves the mattress frame between low and high positions.
